The principles of practical reasoning integrated into real world applications is the basic premise behind Professors Richard D. Rieke and Malcom O. Sillars' fourth edition of Argumentation and Critical Decision Making. The most current theories and research are combined with classic rhetoric to effectively explain the necessary functions of decision making in any given situation. With an increased emphasis on critical thinking, Rieke and Sillars help connect critical decisions with audience values and conventions. Real life examples are used to illuminate the principles of argumentation, ranging from interpersonal discussions to formalized conventions of science and law. A new discussion of language and argumentation highlights language practices that have had the most impact on effective argumentation.
